MPI_Get_address(3)

NAME
     MPI_Get_address - Gets the address of a location in memory

SYNOPSIS
     C:

          #include <mpi.h>

          int MPI_Get_address( location, address)
          void     *location;
          MPI_Aint *address;


     C++:

          #include <mpi.h>

          Aint Get_address(
          void*             location)


     Fortran:

          INCLUDE "mpif.h" (or USE MPI)

          <type> LOCATION(*)
          INTEGER ierror
          INTEGER(KIND=MPI_ADDRESS_KIND) address

          CALL MPI_GET_ADDRESS(location, address, ierror)


DESCRIPTION
     The MPI_Get_address routine gets the address of a location in memory.
     This routine is provided for both Fortran and C programmers.  On many
     systems, the address returned by this routine will be the same as
     produced by the C & operator, but this is not required in C and might not
     be true of systems with word- rather than byte-oriented instructions or
     systems with segmented address spaces.  MPI_Get_address is an MPI-2
     implementation replacing MPI_Address.  It returns an MPI_Aint value,
     which makes it better suited for ABI64.  Currently, the Fortran version
     of this function is implemented only in ABI 64.  This routine accepts the
     following parameters:

     location  Specifies the location in caller memory (choice)

     address   Returns the address of the location (MPI_Aint)

     ierror    Specifies the return code value for successful completion,
               which is in MPI_SUCCESS.  MPI_SUCCESS is defined in the mpif.h
               file.
